Abstract
In this paper, a concurrent dual-band class-E power amplifier is proposed. A distributed matching network is designed without any switch to achieve dual-mode operation. The power amplifier works in the 777-787 MHz and 1710-1785 MHz bands for LTE system. The measured results show 22 and 27 dBm output power at first and second band, respectively. This power amplifier obtains efficiency of 60% in lower bandwidth and 84.5 % in higher bandwidth. A novel matching network is also presented to switch between two different optimum operations for class-E design to improve the efficiency in the lower band.
